How it works
Swap safely in six steps
MEFAI DEX routes your trade to the best price across six chains, scans every token for scams before you trade, and lets you sign in your own wallet. Here is how a swap works from start to finish.
Step by step
Connect your wallet
Use Phantom on Solana or MetaMask and WalletConnect on EVM chains. MEFAI DEX is noncustodial, so connecting only shares your address. We never hold your keys or funds.
Pick a network and tokens
Choose one of six chains, then select the token you sell and the token you buy. Paste any contract address to import a token that is not in the list.
Read the Scam Shield verdict
Before you trade we check the things that get people rugged: can you actually sell it (not a honeypot), hidden sell taxes, whether the team can pull the liquidity, and whether a few wallets hold most of the supply. A clear traffic light shows the risk, and if any source flags it, the worst verdict wins.
Get the best price
MEFAI DEX queries Jupiter on Solana and up to 5 price sources on EVM (LI.FI, KyberSwap, 1inch, 0x, ParaSwap) in parallel, then routes your trade to the best output. We hold no liquidity of our own.
Review, approve and sign
Check the rate, price impact and minimum received, adjust slippage if you need to, then approve and sign in your own wallet. The AI proposes, you approve.
Track your portfolio
See your holdings across chains priced live with 24 hour change. Portfolio is read only and never touches your funds.
Power features
Mefai Copilot
Trade in plain language. Say spend 0.1 SOL to buy USDC and the copilot resolves the token, checks safety, prices it and prepares a proposal for you to sign.
Limit orders and DCA
Set a target price or a recurring buy. MEFAI DEX watches the market and tells you when a fill is ready, then you sign it yourself. No presigned keys.
Cross chain swap
Swap a token on one chain for a token on another in a single flow. Turn on Cross chain, pick the source and destination networks, and route across bridges.
Gasless swaps
No ETH or BNB for the network fee? On EVM you can pay it out of the token you are already swapping. You approve it with one signature in your own wallet, and nothing moves without you. Under the hood this uses a Permit2 signature and a relayer.
Stay safe
MEFAI DEX never asks for your seed phrase or private key, and never moves funds without your signature. Scam Shield fails safe: missing data never counts as safe.
